|
|
Greetings,
Am new here and just wanted to post up a project i just completed.
This is a swiss design made from leopardwood and madagascar ebony. The top is inlaid with solid hippo ivory and gemsbok horn. The ivory is legally obtained.
This bow has a 380/450lb steel prod that was hand made. The prod itself is capable of 550/650lb draw weight but was underdrawn for this goatsfoot lever bow. This is a mid range build for the company and the crossbow is VERY stout. Last week i was putting bolts through 1" laminate oak plywood at about 50 yards.

Contact me for questions or for pricing.

Looks very neat.
How long does it take to build something like that?

Do you have any pictures/diagrams on how to use the lever?

Oh, as in my topic thread I would ask what kind of bolts do you use for practice and what kind of backstop is both safe to use:
No over-penetration and being able to pull the bolts out again ! There is a longer more detailed version of this question on my topic with a slightly different focus on power of crossbows versus longbows.
Oh, and welcome again on your first topic post. :cool:

Thanks for the comments
back stop wise on this bow - yes it is possible to stop them using normal field points and a large burlap bag full of loosely packed plastic bags. But if you use bodkins - no.... the bolt will shatter or go thru whatever your hitting.
quick wmv file is located at: http://www.uccrossbows.com/media/goatsfootcocking_0001.wmv
This shows the goatsfoot in action on two runs, i do not cock the bow however due to being in the front yard during filming and i will not cock this bow unless i am about to fire it.
This bow took about 82 hours to build - this includes all forge work, wood work ect. I had a hand in every aspect of the bow and in many things i was the builder/maker. The heavy prod is the only thing i did not have a direct hand in. This said however, i do and can make prods to about 2000lbs now on the forge.
This is a picture of the lever used [ Linked Image ]
And these are the bolts it fires [ Linked Image ]
And finally - i think the picture just looks cool - this is a 75lb prod coming out of the forge - i was taking the pictures. Credit for the forge goes to Wild Wolf forge in texas. My friend and partner is pictured doing the hot work. http://www.uccrossbows.com/sitebuilder/images/prod7-746x488.jpg
We are currently starting work on a 1700lb crank crossbow, i need to get fair/merchanting over with and then i can devote time on it more. But rest assured i will post pictures :)

I learned to follow your link and see the answer to my question is 73 hours over six months.
Now a different question.
What did you use to bind in the prod?

this bow was built over about 6 months and 73 hours. Its actually now at 82 hours and coming up on 7 months. I have tweeked the bow some and added things not in the pictures as they are about 4 weeks old. At this point it is pretty much done and i have stopped clocking time working on it.
The binding is hemp, i use this as it seems to add to a period look and it is easy to bind, it will shrink, but the downfall to it here in texas as the humidity rises - it seems to loosen. Over all i expect to rewrap this prod about every 300 shots. Which on a moderate crossbow (350 to 450 range) is a lot of shooting. <--- this is a conservative number of shots and mainly due to the summer humidity. Results in dry areas will increase shot count.
