I saw a plan for a homemade Moxon vise using pipe clamps and I wouldn’t ususlly Ask this type of question because MDF might not be strong enough, but I have a ton of MDF left and I would love to make this without spending much..

Or should I just go and get 1/2” PLY!!!!!!

Here is the plan im looking at

Give it a try w/ MDF, if it doesn’t work for you then you can always rebuild it with ply

You can get pipe clamp fittings from harbor freight for something like $9/pair. Then get whatever length of pipe you want from Lowes/HD. Be sure to have them cut it for you and thread the ends (they do it for free).

Don’t waste your time with mdf. It splits, will never be strong enough.

I was amused at “Jay’s Custom Creations” for asking for payment for a plan idea that has been done perhaps a thousand times over by others.

Last I checked on Jay’s site (30 sec ago) the plan for the Moxon style vise was in the free section.
So, if you do not have anything nice to say, better shut up.

If you click the link in Ed’s post, it takes you directly to Jay’s site so you can open or save the plan.

He is not charging for it.

The plans are free. Striaght MDF might not hold up in the long run. MDF has good compression strength but not good tensile strength. I bet if you backed the MDF w/ plywood it would hold up pretty well.

^I agree that you probably could make the mdf work, but why?
The amount of material needed is so minimal, there is no reason not to use a better material.

Radu:
Ahem, well if you bothered to look further, he is soliciting contributions. But if you want to get something for free from him, you have my blessings.
Odd, how your advice was worded, about not having nice things to say.
EdWood:
I’d encourage you to look for some solid hardwood for your movable jaw; it doesn’t have to be pretty but I’d be afraid of plywood flexing and denting your work.

If you double up the mdf, it will probably be plenty strong. 1.5” of mdf over a small span is pretty darn stiff

The MDF will probably work but the Moxon requires so little wood I wouldn’t even bother. I don’t get why it has to slide too? I just clamp mine the the bench so the back jaw just hangs off the edge. I think the pipe clamps are going to be annoying to adjust too. You are going to have to hold your stock and at the same time tighten the clamps. The weight of the front jaw is going to pull down on the clamps and I have a feeling it’ll get old soon.

I made a Moxen last winter and originally buried a 1/2” nut in the back jaw (on the back) and then used 1/2” acme rod to hold and tighten the front jaw. What a pain! the weight of the front jaw (thick walnut) pulled down on the screws and it made tighten them very hard. I dumped all of the hardware, saved the wood, and bought the Benchcrafted Moxen hardware. What a difference! The thread bolts to the back jaw which holds the front jaw up. The wheels in front are very heavy and with just a spin they lcm the wood in place.
