@pline,
Sir,
Can the HK 6 in 1 be actually used to make anything?
I have a few basic problems
1. Poor centering. When you tighten the chuck on say a 1/4" wood or aluminium dowel, unable to get it to hold a true center on the tailstock
2. Supplied tool does not cut even wood, let alone aluminium
3. Units mounted on bed move despite tightening as much as i dare
4. Adjusting belt tension changes the motor shaft alignment, making the belt slip sideways and dismount after a few seconds run.
Failed so far to make a simple thing like two cones for a prop balancer. (Been some 45 years since last working with a lathe - at a Kharaati's workshop! Can't remember whether the tool needs any sharpening/hardening before use...)
Grateful for any help.
Regards
Sir like i had mentioned in my earlier post, the HK 6 in 1 is more a toy and a copy of the Playmat from the cool tool Austria.
Even then I tried some improvements on it as mentioned in the thread, but it lacks rigidity and nothing serious can be done on it. Finally I researched online for a copy of the Unimat metal line, and came across the Zhouyu brand of machines which are exact copies of the Unimat Metal line and are all metal machines and i have been pretty satisfied with this all metal machine from Zhouyu's performance.
Finally I spoke with the manufacturer in China and thought of re-selling their complete metal line both Cnc & machines, and they have an affordable price range suited for us Indian model engineers. (You can visit my website
http://menco.in for details on their machines.)
Coming back to the HK 6 in 1 here are a few things that I have tried:
1. built a speed regulator and reverser using a LM338K (see thread)
2. bought some HSS 4mmX4mm cutting tool blanks from the local market, which i have ground myself on my standard bench grinder for facing, parting, grooving etc.
3. bought 4mm, 5mm & 6mm 4 flute endmills for the mill
4. built a modified tool post, the plastic tool holders often come loose and have absolutely no strength (see thread)
5. attached the machine to a 1/2" thick hardwood base with nylon pedestals
Will try and keep modifying it until i run out of patience and money! Will keep posting.
