Hi Paul
Regards your CL3 motor upgrade you have a few options.
1. The motor that Record use is a 0.75kw 1500rpm motor made by Lenze. You can contact Lenze direct to see if they will or one of their agents can supply this motor direct to you. There contact information is: Lenze Ltd. Priory Business Park. Bedford MK44 3WH. Tel:01234 753200. email sales@lenze.co.uk
2. Haydock Converters supply a full conversion kit for the CL3 for around £350 which includes the motor and inverter.
There contact information is : S Haydock Tel: 01254 201888. email converters@shaydock.fsnet.co.uk or
www.haydockconverters.co.ukI believe they are very helpful and may just suppliy the motor if this is what you want.
3. I took my old single phase motor to a local motor supplier and they supplied the motor and machined the casting that fits to the headstock and also bored the pulley and reverse fitted the pulley and also supplied the inverter for about £250. You could have this done and any motor supplier/ rewinder should be able to do this and there is usually at least one in most towns. It may sound daunting but it is quite easy for these people to do.
I hope this helps and if you need any further information please contact me.
Regards and a Happy New Year
Terry
