    Hope all our community and their fam and friends are well!

    Would love to know what the clever crossbow builders here are up to in their workshops if confined to home?

    I have just restored a vintage Whammo Powermaster myself, and for safety sake, keeping it as a wall hanger only. Tested it a couple of times with a full face guard though, and is actually quite a sweet shooter!
    Stripped, stained and refinished stock, polished prod and all metal parts, and made a new string. Pics soon.

    Next project is carving an Australian Blackwood stock for my Astro Daco Hornet.
    Will refit the original prod, though build a better mounting system, and use the factory trigger mech which works well.

    For your second crossbow what do you plan to use as the mounting system? I know the Astro Dacro Hornet the prod is made from fiberglass.

    The old Wham O crossbows suffered from two dangerous faults:  Some models had insufficiently hardened sears... the lock would fail when you released the safety
    The second problem was fatigued aluminum prods.  I've had lots of experience with aluminum prods. Occasionally old ones fail.  Usually that means they just bend and stay that way.  Occasionally one actually breaks (usually at the middle) For that, there are two possible solutions: (well three if you count hanging it on the wall) either fit a leather strap down the length of the prod (backside) That way if the prod breaks, it won't come back and hit you... that's what medieval bowyers did.  
    The other solution:  Send a letter of enquiry to Garvin's Slo Bows and see if they still have steel replacement prods for Powermasters.  Yes, I know Garvin can be infuriatingly slow sometimes, but he's honest, and is the only supplier I know who has replacements for Powermasters. With a new steel prod, you can shoot to your heart's content.  Just be careful to keep the bow pointed downrange when you release the safety... at least for the first few shots... and enjoy.  Whamo powermaster was my very first crossbow.  It gave me many hours of enjoyable shooting.  Geezer.

    The factory spec Daco mounting system leaves much to be desired imo. Plan to make a steel nose cone of sorts similar to the old Barnett Mk1 Wildcat to improve limb security and angle to the deck.

    If I was to shoot the Whammo I would probably cover the prod with a couple sleeves of shrink tube. It's a pity the "Duralum"  alloy had such fatigue and reliability issues. Wonder if the first Barnetts, Hortons and Jayhawks had problems? The 80's Crissbow Crossbows used a similar material in both their recurve and compound models, but have never heard of failures here.
    Can certainly see problems arising with the string latch on the Whammo, very thin sheet steel, looks like it was folded from tinfoil!

    Those rolls are filled with sand.

    Well, so far I've managed to spend a few hours just cleaning my work-space. Normally I only get a few minutes in the 'shop in any week, so, on the rare occasion I get out there I normally spend my time working not tidying. The state of the place is just embarassing! Next I'm going to 'rotate' my timber store and select a few pieces for a pin-lock bow to work in parallel with my long-term composite-bow project.
