Part 1: Bandurria Picolo

06-25-2013 12:36 PM by BertFlores58 | 7 comments »

Quite a break for me… without post in the lj. I was just reading and viewing to be updated. Here back to same hobby. Glad that the old musical instrument was taken cared by my late father in the province where i grow up. With the condition that is nearly beyond repair, made myself available to try restoring it. In return, the challenge is really interesting. Bandurria is a spanish origin. The Philippines made a variation to make it 14 strings from original of 12. The body ...

Part 2: Violin

06-26-2013 03:40 AM by BertFlores58 | 5 comments »

My father being an all-around musician, bought 3 violins for us. Of the 3, mine was totally destroyed, My brother’s was already restored (I have already done it.) but the last one which was my father’s is now in my possession. This is so much special as this was loved by my father and been played much older than me. The only problem that I have seen is the glue which had given up due to time. Here is the situation after I had disassembled it. Regret that I was not ab...

Part 3: Bandurria - Key of E

07-01-2013 04:17 AM by BertFlores58 | 3 comments »

As you know, this series is not a real sequel where numbering is not arranged chronological. Just look and see where the continuation of each. Though, all of the posts deals with my new line of skill development in restoring musical instruments from my family heritage, there are a lot of learning ideas based on my experiences. I am just an amateur that looks to the possibilities of rectifying those difficulties using only available resources. So this is one new instrument again…. ...

Part 4: Bandurria Picolo Progress

07-01-2013 05:44 AM by BertFlores58 | 5 comments »

Here I am back with the restoration of the Picolo (Soprano).. This is the continuation of this blog. Last Saturday and Sunday, I made a big progress giving attention to the back plate and assembly. Here are the photo and some of my important notes on them. The back plate with the supports and ribwork. Not to many clamps were used here. The back plate completed. In order to add more strength on the front plate (soundboard), support been added. I hope this will not affect the s...

Part 5: Violin 2 - The Jig for the ribs

07-01-2013 08:41 AM by BertFlores58 | 3 comments »

Here is the progress of the violin restoration as the continuation of this blog. In the process, the need for making the ribs of this violin is a must. After several try of bending the wood, there is no way but to make a jig that will hold the steamed wood while it is hot. So here are some of the photos: I made this using a two boards cut into shape of 3/4 inch plywood and laminated together. That was too thick. I realized later that the correct thickness is just one and 1/4 inch so ...

Part 6: Bandurria Rib Glued

07-06-2013 03:15 PM by BertFlores58 | 4 comments »

Here is the progress of the Bandurria picolo continued from this blog. Nothing much done but this is the most crucial part in the assembly. The ribs both the starboard and port (left and right side) is difficult to clamp and glue. I have to think a lot on how to do it. The photos below will explain it. As it looks like a mummy wrap around by a garter (1 inch width). How long? I dont know. Aside from the garter, there is also a rubber strips of 1 inch width and 1/8 inch thick. Als...

Part 7: VIOLIN JIG - The CLAMP for bending

07-06-2013 03:45 PM by BertFlores58 | 3 comments »

This is the progress for the previous blog I made. Just look at the pictures. The long bolts are pedestals and pins for the clamps. I used the 3 holes to make it standing. It started from a flat steel bar drilled with three holes. Then bended squarely on both ends just enough to be away so that it will accomodate the small ebony piece that will be the push block. A push bolt with a knob was taken from the locking screw of scrapped pedestal. The nut should have been welded ...

Part 8: Violin 2 - Jig for the ribs on action

07-15-2013 05:17 AM by BertFlores58 | 4 comments »

Took me a little while to do the steel work on the jig. Have to make the somewhat C-clamp with push block. Cutting threaded bars and looking for the nuts. Shaping the push blocks (made from ebony) become tiresome after making 16 pieces. These are made from scraps. Here are some self explanatory photos… I give notes on some important aspects and ideas that you can grab suited for your project and availability of materials: Notes: 1) The piece that was bended was narra ripped by ...

Part 9: Violin 2 - Assembly of the body

07-16-2013 03:35 AM by BertFlores58 | 3 comments »

After the bouts or sides or ribs been done, the next is to assemble the whole body including the neck and scroll head. CLAMPS. Though I can use spring clamps and other models, the problem lies in the limited clamping space of the plates. The flat surface (perpendicular portion to the ribs) of the plates that are parallel to each other is only 3/8 inch or less measuring from the edges towards the center. This gives a small space for clamping which often times spring clamps and F-clamps s...

Part 10: Finally the violins are restored completely

07-24-2013 05:03 AM by BertFlores58 | 8 comments »

The final assembly came out very good. The violin 2 passed thru my expectation with respect to sound and strength. I am happy how it came out. The sound is perfect and high enough. The vibration of the plates including the bottom is remarkably balanced. I can fell the effect of the bridge prolong vibrations. The last phase came up with the gluing of the bottom plate, the fretboard, and the fixing of the tailpiece. I made the bridge accordingly using a special medium hard wood. ...

Part 11: Octavina

08-06-2013 08:05 AM by BertFlores58 | 5 comments »

Octavina is a family of bandurria. Just simply an octave lower than a bandurria. It belongs to a 14 strings family that consist of Octavina, Laud, and Bandurria. Though, nothing so special compared to an acoustic guitar construction, except that this should be a little bit stronger and smaller than that of a normal guitar. The frets are exactly spaced as the guitar depending on the total span of the frets. However, the notes are not so arranged to make chords but rather to produced a v...
